- Multiple variables assigned to the same register using `:reg` in `rlet` (or overlapping with `self` in a behavior) will now be merged to a single variable instead of causing a compiler error. Variables will have their own type, but they will all be an alias of the same exact register.
- Stack arrays of uint128 will now be 16-byte aligned instead of sometimes only 8.
- Inline arrays of structures are now allowed with `stack-no-clear`.
- Creating arrays on the stack now must be done with `stack-no-clear` as they are not memset to 0 or constructed in any way.
- Creating arrays on the stack now must be done with `stack-no-clear` as they are not memset to 0 or constructed in any way.
- The register allocator has been dramatically improved and generates ~5x fewer spill instructions and is able to eliminate more moves.
- Added a `(print-debug-compiler-stats)` form to print out statistics related to register allocation and move elimination
